Marco Rubio’s campaign quickly moved to capitalize on his strong finish in the Iowa caucuses Monday night, wasting no time in sending a message to his establishment-friendly rivals that the Florida Senator is the only candidate who can stop Ted Cruz or Donald Trump.
“It’s now a three-person race,” Rubio campaign spokesman Alex Conant told TIME. “One of these three people will be the nominee. If other campaigns don’t want to accept it, that’s fine, but it’s a three person race.”
Rubio’s third-place finish with 99% of precincts reporting was in line with expectations the campaign had set in terms of pole position. But in finishing just 1 point behind Trump and not far behind first-place Cruz, Rubio emerged as a winner in Iowa, where the caucuses have long been almost as much about beating expectations as they have about winning outright. And it was easy to interpret the Conant’s comment as a missile directed toward Jeb Bush, Chris Christie and John Kasich—other establishment-favored candidates who will find themselves under growing pressure to exit the race if they don’t perform well in the New Hampshire primary next week.
Addressing enthusiastic supporters in Des Moines, Rubio gave what amounted to a victory speech.
“So this is the moment they said would never happen,” Rubio said. “The people of this state have sent a clear message. After seven years of Barack Obama, we aren’t waiting any longer.”
Rubio used the speech, broadcast live nationwide, to make a clear argument that he is the most electable Republican. “When I am our nominee, we will unite our party, we will grow our party, and we will defeat Hillary Clinton or Bernie Sanders,” he said.
As votes trickled in throughout the night, Rubio campaign officials expressed glee at his numbers.
“Damn good night for @TeamMarco!” Rubio campaign manager Terry Sullivan said on Twitter. “And it looks like its gonna keep getting better based on the precincts still to come.”
“We blew past all our vote goals an hour ago,” top strategist Todd Harris said on Twitter. “Feeling very good. We are still climbing. #teammarco #rubiowa.”
